编者按:直线与圆锥曲线联系在一起进行考查的综合题在高考中多以压轴题的形式出现,主要涉及位置关系的判定、弦长问题、最值问题、轨迹问题、对称问题等,突出考查数形结合、分类讨论、函数与方程、等价转化等数学思想方法.因此,这类题目综合性强、难度大,对考生的计算能力要求高,是历年高考考生失分最严重的题型之一.这部分内容你复习得如何?如果还不够好,那就再认真地学习一遍,因为它们真的很重要. Editor’s note: The combination of straight line and conic curve examinations in the college entrance examination in the form of pressure axis problems, mainly related to the determination of the location, chord length, the most value, trajectory, symmetry, etc., highlight test Therefore, these kinds of topics are comprehensive, difficult and require high computational power of candidates, which is the most serious type of problem that the college entrance exam candidates lose in the past years If you are not good enough, then study again carefully, because they are really important.
